推送器接收具有空值的事件

Question

我正在使用 laravel 5.8 版本。我正在向推送器发送消息，但让推送器接收事件 {"message": null}。这是我的 broadcasting.php 文件

'connections' => [

        'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
//                'cluster' => env('PUSHER_APP_CLUSTER'),
//                'useTLS' => true,
                'cluster' => 'ap2',
                'useTLS' => true
            ],
        ],

有我的 chatevent.php 文件。

 namespace App\Events
    use Illuminate\Broadcasting\Channel;
    use Illuminate\Foundation\Auth\User;
    use Illuminate\Queue\SerializesModels;
    use Illuminate\Broadcasting\PrivateChannel;
    use Illuminate\Broadcasting\PresenceChannel;
    use Illuminate\Foundation\Events\Dispatchable;
    use Illuminate\Broadcasting\InteractsWithSockets;
    use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class ChatEvent implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    public $message;
    public $user;
    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($message, User $user)
    {
        $this->$message = $message;
         $this->$user = $user;
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

这是我的 bootstrap.js 文件。从 'laravel-echo';

导入回声

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    // broadcaster: 'pusher',
    // key: process.env.MIX_PUSHER_APP_KEY,
    // cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    // encrypted: truebroadcaster: 'pusher',
    broadcaster: 'pusher',
        key:'REDACTED',
        cluster: 'ap2',
        encrypted: true
});

我向推送器发送消息的控制器功能。

public function send()
    {
        $message = 'hello';
        $user = User::find(Auth::id());

        event(new ChatEvent($message, $user));
    }
}

如何解决？？？？

Answer 1

我认为您编写事件的构造函数 class 有误。在这里，您在 message 和 user 变量

之前放置了额外的 $

    public function __construct($message, User $user)
    {
        $this->$message = $message;
        $this->$user = $user;
    }

应该像下面这样

    public function __construct($message, User $user)
    {
        $this->message = $message;
        $this->user = $user;
    }

推送器接收具有空值的事件

Pusher receive event with null values

laravel

vue.js
